METHOD 0F DESTROYING DISEASE-GEWIS IN SANITARY APPLIANCES.

SPECIFICATION forming part of Letters Patent. No. 346,202, dated April 20, 1886.

Application filed Srptember itl. lF.

To all whom it may concern:

Be it known that I, ABRAHAM EDWARDS, a citizen of the United States, residing at New York, in the county of New York and Slate of 1New York, have invented certain new and useful Improvements in Methods oi' Destroying Disease- Germs in Sanitary Appliances, of which the following isaspecication, reference being had therein to the accompanying drawings. wherein- Figure l is a vertical transverse section of a trap embodying my improvements. Fig. 2 is a transverse section showing induction-pipe arranged cccentrically to the body of the trap; and Fig. 3 isa section of a portion of an upper part of a water-closet bowl having a mercuryscaled cover, showing mercury-trough embodying my invention.

My invention has relation to mercury-seals for water closets and traps in general, but more particularly to the trap shown and described in Letters Patent cf the United States dated October 23, 1883, No. 287,369. In this patent it is stated that chloride of sodium is present in sewage, and that the decomposition of the chloride of sodium, as it comes in contact with the mercury, furnishes chloride enough to form with the mercury a minute quantity of corrosive sublimate, which serves as an additional protection, inasmuch as it gradually accumulates upon or spreads itself over the inside walls of the trap in the form of a film, which destroys the development of the bacteria or the fungus growth from which emanate the disease-germs found in sewer gas. The corrosive sublilnate so formed depends for its formation upon the presence in the sewage of the chloride of sodium, and consequentlynf it is present in exceedingly minute quantities, or if not present at all, the formation of the sublimate is practically either too minute to be of any benelit or is wholly wanting.

To avoid the disadvantage of limited or no formation of the sublimate in mercury-seal traps is the object of my present invention, and to accomplish this I do not depend upon the chloride ot sodium in the sewage, but make such sodium or other suitable chloride compound an essential element or a. component part ol' the substance composing the trap-body or its mercury-containing chamber,w hereby a positive supply of sodium is provided to keep Serial No. 7.514. (No modi-l.)

up the chemical action between it and the mercury to form at all times thc requisite quantity of corrosive subliinate for destroying or retarding the fungus growth in the trap.

My invention accordingly consists of a mercury-seal trap having a body or a mercurycontaining chamber made ol` a chemitzallyprepared substance of which chloride ofsodinm forms an element. the material used beingI pre1- erably vulcanized rubber.in which the sodium incorporated beforethe rubber is vulcanized.

My invention further consists of the combinatioincoiistructiou. and arrangement ot'parts, as hereinafter described and claimed.

In the drawings, Arepresents the mercuryseal trap, having preferably a top and a bottoni section, Baud C, respectively. screwed or otherwise secured together, as shown at a, with an interposed gum gasket or packing, a', for making an airtight `joint.

The top section, l5, is preferably made of metal of anysnitable kimhliaving a side eduction-pipe, b, and a central induction-pipe, Il', into which serewsa pipe. b2, depending into the mercury E in the bottom of section C. The lower inner edge of pipe b'fis beveled, as shov` n at Il, to produce a sharp lower edge or end for pipe b, to afford easier displacement of the mercury by a column of water in pipes b Il".

The bottom section, C, is the mercury-containing chamber, and it is preferably iliade of vulcanized india rubber or other material either chemically or otherwise prepared, ot' which, preferably, chloride of sodium forms a component ingredient, or which is incorporated in it when prepared. If vulcanized rubber is employcd,the chloride of sodium is preferably added to the rubber before being vulcanized. Any suitable proportion of the sodium may be used with the. rubber. I have found that seventy parts of tine para, eight of electro-silicon, two of lamp-black, eight of zinc, teu of sulphur, and two of chloride of sodium give a trap-body suitable for mypurpose; but these proportions may be varied as desired, or according as a greater or less quantily ol` corrosive subliniate is required in the trap.

rlhe chloride of sodium being present in the prepared trap-body or its mercury-containing chamber, a supply of suoli material is always at hand for gradual decomposition by the mer IOC cnry to form corrosive suhlirnntc .fis ncrdffd. t AS the lutttr is 'nrint-d it grznltmltv spi-mills itstlf in :i tilnrlilu tinin ort-r thv inni-t' nils nl' tht tlniinln'r ('.und :ilsu mm' t hv .vnruw nl the intim-tion liipt. thus d-. trt \inj t'nngns growth ur list-:tsc-gt-rtns t-ntcring nr txinting in thtl trztp.
